TUG-ADJUSTER FOR HARNESS.

SPECIFICATION forming part of Letters Patent No. 237,086, dated February 1, 1881.

Application filed May 15, 1880. (No model.)

' To all. whom it may concern:

cation of my invention. Fig. 2 represents a longitudinal vertical rsection of the same.

The same letters denote the same part-s' in all the drawings. v

Myinvention relates to the tu gs or straps by which the body -harness of draftanimals is connected with the vehicle to be drawn; and the object of it is to provide ameans by which the length of the connection may be readily varied while maintaining security 'of attachment to the vehicle. This object I .attain by extending the base of the tug-hook (or connection of thetug with the hame) into a bar having attachments adapted to interlock with corresponding attachments on the tug-strap.

In the d rawings,A denotes a bar, havin g at one end the tug-hook c, by which it may be attached to the haine. Its upper surface, B, is depressed so as to form a groove or channel, in which the tug-strap may have a longitudinal but no lateral motion. llhe middle part of this surface maybe cut out, as shown inthe drawings, so as to leave merelya track at each side for the strap to run on. The sides of this channel or groove are connected at intervals by cross-bars or bridges C. The tug-strap D is made of suitable width to slide easily, without lateral motion, in the channel B, and has y at the end nearest the hame a hook or catch,

E, of suitable size and shape to take firm hold of either of the bridges C, but readily detachable from them by being pushed backward.

tug a spring, F, whose elasticity is sufficient to press the catch firmly against the bridge, so that the strap can have no motion in the channel, except by applying a compressive force directly to the spring. The tug therefore cannot be loosened by any motion of the animals or of the vehicle, while by rmly graspingthe catch and spring and drawing the tug back- 'Eward it is at once detached, and may then be hooked onto another bridge backward or forward of that from which it has been removed. Then, by releasing the spring` and catch from the grasp, the tug is held rmly in its new place. It is obvious that this device may be applied to any apparatus in which a flexible connection of variable length between two points is desired.

' What I claim as my invention, and desire to secure by Letters Patent, is y 1. The bar A, having the hook a and channel B, in combination with the strap D, capable of longitudinal motion in the channel, the spring F, afxed to the under side of the strap, and a stop-catch, one member of which is secured to the upper side of the strap, and the other to the bar above the strap, whereby the two parts of the catch are caused to interlock by a pull on the strap under the outward pressure of the spring, substantially as' described.

2. The bar A, having the hook c, channelB, and bridges C, in combination with the strap D, adapted to have a longitudinal motion in the channel, and having the catch E, adapted to lock on either of the bridges, and the spring F, adapted to hold it locked, al1 constructed, arranged, and operating substantially as described.
